I'm guessing if you played a bunch of Alchemy-heavy games, you'd change your tune about these two (in terms of how they play in Alchemy-heavy games, not where they appear on your power rankings).
Ah, well maybe we are just both misunderstanding - I am not talking about alchemy-heavy games there, still just going on the all-random!
Disagreements so far:
Feast: Yes, Silver is better, but I don't always want Silver. I just want to guarantee I get that Witch or Wharf or whatever next shuffle. Maybe I'm doing a Scrying Pool engine and I want to ditch all my Treasures, not add to them.
Well, sometimes you don't want silver, but you also need to not want any other 3 or 4 cost cards. And there really aren't many games where you don't want any 3 or 4 cost cards, *really* don't want silver, and are very focused on getting to $5 *one time*. Hey, it's not that they don't exist, but they're rare, and feast usually isn't *that* much of an upgrade even in these situations. Of course the card is a useful thing to have in your deck, but it rarely meets the opportunity cost.
Mine: Mine is a great card! Yes, there are other cards that are more powerful than it, and it may just be a "terminal Copper", but the point is to get it early (your first $5, preferably) so it can be used often. It's one of the lynchpins of the First Game engine, turning your Coppers into Golds for Remodel to turn into Provinces.
I have no idea how Mine can be a 'great' card. Maybe your definition of 'great' is really loose, and most cards are 'great'. Getting it early, man, that's not my idea of a "I'm going to win this game" plan. Sure, sometimes it's the best move, but I can't recall ever having been like 'Sweet, I got 5, I can get my mine!' or paying $6+ for mine, which is something I will do with virtually every other 5-cost. As for it being a 'lynchpin' of the First Game engine... well, it's useful int hat engine, but I *really* don't think it's a lynchpin - and that is a board which could almost have been designed to show the card off. Again, has it's uses, but they can't all be the best card. Something has to be last.
Pirate Ship: This can be underrated and overrated. It doesn't need to be in a 4-player game, and there doesn't need to be +Buy. Just get a couple of them, hit your opponent 4-5 times, and now you're buying a Province whenever it's in your hand.
Problem is, this consistently loses to Big Money *with no help*, which is supposed to be the strategy it's countering, right?
Philosopher's Stone: This is great in sloggy games. True, you won't see it or your Potion very often, but when you do, It can easily add a Province to your Gardens deck.
I disagree. It's great to *have* in sloggy games, sure. But you are now wasting a card on that potion, and probably one of your key early ones. And then you are buying a PStone, which saps more time. And then you get something which is worth a reasonably high amount of money. But every potion and P stone could have been, say, another gardens. If it's a slog mirror, you are putting yourself too far behind. If you are playing a non-mirror, poaching provinces is not really in the game plan anyway - your alt VP card should be worth at least almost as much as province, and your province helps them end the game on you. I mean, I have found some uses for it in mountebank games with nothing going on, but you sort of need ti to fall right, and it's still not the hugest of improvements.
Taxman: You don't understand this card.
Care to enlighten me?
Trade Route: Trashing is nice at the beginning of the game, though admittedly Forager is essentially the better version of this. Whether to buy an Estate or not becomes a strategic decision (which I find interesting), but even just being able to trash a little can help you out, and then it becomes a powerhouse later in the game.
Trashing IS nice at the beginning of the game. Unfortunately this card doesn't do it for you. You are adding what is essentially a worthless card, so next shuffle you actually have MORE junk, the shuffle after you are only back to even, and the shuffle after that you finally see some thinning. And it's terminal. It's absolutely not worth it at 0. And trashing one, getting a buy and a couple of coins isn't really my idea of a powerhouse in the late game - the problem is, it usually has cost you a $5 in terms of opportunity, either because you bought it late when it was good (most often you are producing 5 most every hand by now) or you bought it early instead of something else which could have propelled you to $5 where this did not.
Rats: You read my article on this, right? The whole point of this card is for other things to trash it. So yes, without cost- or type-caring TfBs in the kingdom, Rats is useless - but there will usually be some sort of cost- or type-caring TfB in the kingdom. Is it worth the opportunity cost to buy a single Rats before buying your Bishop or Salvager or Apprentice? YES.
I did read your article. Now, let's count the cards which Rats is potentially helped by: Remodel, Swindler, Saboteur, Upgrade, Salvager, Apprentice, Transmute, Watchtower, Bishop, Expand, Forge, Remake, Develop, Trader, Farmland, Procession, Graverobber, Rogue, Stonemason, Butcher, Governor. Okay, I didn't include things like Trade Route, where the card you get from trashing it might be a boon, but I included stuff like Rogue and transmute which probably shouldn't be in here, really. Anyway, there's 21 cards here, and given we have 9 kingdom spots left and there are 204 cards total... There's about a 63% chance that one of these cards will appear with Rats. Now if we take out a bunch of these which are sort of ridiculous includes, I think the actual list of cards that might make me want to go rats is more like, Vineyard, Scrying Pool, Remodel, Upgrade, Salvager,
Apprentice, Bishop, Forge, Develop, Trader, Butcher. Now, I think I'm being generous here, and this is 11 cards, but let's fudge and say there are 15. This would get you to a 50-50 shot of having one. But the problem is, I usually STILL would rather do something else. I dunno, you're probably right in that I am under-rating these guys, but I stick by them being pretty bad.
